Simulation Features

SVDynamic represents a revolutionary new method of slope stabilityanalysis that extends the capabilities of limit equilibrium methods ofanalysis.

Slope stability analysis is an integral part of many geotechnicalengineering studies. Although numberous methods of analysis exist,the failure mechanism is still not fully understood.

Force and moment equilibrium methods can be ap plied to thestability problem and will provide a computed factor of safety. Alllimit equilibrium methods rely on a critical assumption regarding theshape of the slip surface. The normal force on the base of the slice isdetermined by applying statistical equilibrium to a slice from thesliding mass. The location of the critical sli p surface is determined bytrial and error.

SVDynamic makes use of a finite element stress analysis (SVSolid) tocompute the stress state in a soil mass. Various soil models can beused for the computation of the stress states. SVDynamic makes useof dynamic programming to calculate the most probable location of

the slip surface. No assumption needs to be made regarding theshape of the slip surface since the determination of the shape is partof the solution. Non-circular slip surfaces may be computed fromirregular soil layering.

The SVDynamic solution provides a global factor of safety as well asthe distribution of the local factors of safety along the critical slipsurface.
